摘要

A touch sensor for a touch display is provided which includes an optical element including at least one electrically conductive layer, the at least one electrically conductive layer being partially reflective and partially transmissive with respect to incident light; and sensing circuitry electrically coupled to the at least one electrically conductive layer to determine positioning of a finger, hand or other type of pointing device relative to the optical element.
